SUPPORT FOR REFRlGEFlATlNG-CHAIVIBERS.

SPECIFICATION forming part of Letters Patent No; 764,923, dated July l2,1904.

Application filed December 3, 1903. Serial No. 183,599. (No model To all1071/0711, it may concern:

Be it known that I, VICTOR A. DE OANro, a citizen of the United States,and a resident of Union Hill, (IVeehawken P. 0.,) in the county ofHudson and State of New Jersey, have invented a new and Improved Supportfor Refrigerating-Ohambers, of which the following is a full, clear, andexact description.

The invention relates to refrigerators; andl its object is to provide anew and improved movable support for use in ice-boxes and other1'efrig'erating-chambers-such, for instance, as are used in hospitals,morg'ues, and the like-and arranged to permit convenient removal of thesupporting-tray from the refrigerating-ehamber or replacing' it therein.

The invention consists of novel features and parts and combinations ofthe same, as will be more fully described hereinafter and then pointedout in the claims.

A practical embodiment of the invention is represented in theaccompanying drawings, forming a part of this specification, in whichsimilar characters of reference indicate cor-V responding parts in allthe views.

Figure l is a side elevation of the improvement as applied to arefrigerating-chamber such as is used in morgues, hospitals, and likeinstitutions. Fig. 9. is a transverse sectional elevation of the same.Fig. 3 is an enlarged sectional side elevation of the improvement,showing' the tray and frame within thechamber. Fig. 4 is a perspectiveview of the tray; and Fig'. 5 is a perspective view of thesupporting-frame, parts being shown dismembered.

The refrigerating-chamber A, of any approved constructiomis providedwith the usual door-openings A', each adapted to be closed by a door B,and through each opening is adapted to be moved a tray or likesupporting structure O forsupportingacorpse or an article or a substanceto be kept cool in the chamber A. The tray O shown in the drawingsconsists of a shallow body O', preferably made of sheet metal and havingthe upper ends of the sides and ends attached to tubular side rails O2and end rails C, connected with each other, of which the side rails O2are somewhat extended beyond the end rails O3, and the eX- tendedportions are connected with each other by cross-bars O4, forming handlesfor conveniently carrying the tray and its load about or otherwisemanipulating the tray, as hereinafter more fully described. The siderails C2 of the tray O are adapted to travel on longitudinal guidewaysD, preferably in the form of grooved rollers, journaled on studsattached to plates E, secured tothe side walls A2 of the chamber A, asplainly indicated in Figs. l and 2.

Underneath the tray O is arranged a frame F, preferably rectangular inshape (see Fig. 5) and formed by side rails F' F, a front cross-bar F2,and a rear removable cross-bar F3, the side rails F of the frame F beingmounted to travel on guideways G, preferablyv in the form of rollers andsimilar to the guideways D and likewise journaled on studs carried bythe plates E.

On the front cross-bar F2 is hung a gravitycatch H, adapted to beengaged by a roller or similar projection Oi', held on the under side ofthe body O of the tray and located approximately midway between thefront and rear ends of the tray.

Vhen the several parts are in the position shown in the lower portion ofFig. l--that is, the tray O and frame Fare contained within the chamber'A-and it is desired to remove the tray from the chamber through the opendoor-opening' A, then the operator takes hold of the front cross-bar C*of the tray and pulls on the same, so as to slide the tray lengthwiseout through the door-opening A', and when the projection C" comes incontact with the catch H then on the further outward movement of thetray the frame F is carried along, the latter sliding along' on itsguideways G. I/Vhen the tray and frame reach the outermost position,V asshown in the uppermost portion of Fig. l, then the tray can be readilylifted olf from its first roller on the guideway D and off the frontcross-bar F2 of the frame to carry the tray and its contents to adesired 95 place.

On the under side of the body O of the tray are arrangedlongitudinally-extending guide ways or rails C, adapted to travel onfriction-rollers Fi, journaled on the front cross-v bar F2 of the frameF, so that when the tray is returned to be passed back into` the chamberA then the rear ends of the said rails C are placed on top of thefriction-rollers F* of the extended frame F, and then the operator bypushing on the front cross-bar C4 can readily slide the tray inward, sothat the side rails G2 quickly engage the guideways D in the chamber A.When the projection C" moves in contact with the upper end of thegravity-catch H, then it merely swings the catch H in a horizontalposition for the projection C5 to pass onto when the tray C has advancedsufficiently far inward for the outer cross-bar C4 to come over thecross-bar F2 of the frame F, and then the operator can also take hold ofthe cross-bar F2 to shove the frame and tray simultaneously into thefinal position within the chamber A, as indicated in the lower portionof Fig. l. (See also Fig. 8.)

In order to prevent the frame F from tipping over when in an outermostposition, retaining-rollers G are provided, journaled on the frame E andlocated above the rollers or guideways G, the rollers G/ engaging thetop surfaces of the side rails F of the frame. The rollers G' also formstops for the outward movement of the frame F, as the rear cross-bar F3abuts against the rollers G at the time the frame F has moved into anoutermost position. (See Fig. l.)

In order to prevent the frame F from leaving its guideways, the rearrollers of the guideways Gare connected with the rollers G' byretaining-plates G2, extending along the inner faces of the side railsF/ of the frame F, and similar plates G3 connect the front rollers ofthe guideways G and D with each other.

Then it is desired to slide the tray C out of the chamber A withoutcarrying the frame F along, as above explained, the following device isprovided: Within the chamber A, at the inner face of the front wallthereof, is arranged a trip I, pivoted at Il on a suitable bracket E',attached to the inner face of the front wall of the chamber, as plainlyshown in Fig. 3. On the free end of the trip I is arranged an angulararm I2, adapted to engage the gravity-catch I-I, when the trip I isswung upward into the position shown in Fig. 3, to hold thegravity-catch H in a hori- Zontal position, so that when the tray C isdrawn outward its projection C" passes over the top of the gravity-catchH without taking the latter and the frame F along. The trip I when in anuppermost position extends into the door-opening A', as plainlyindicated in Fig. 3, and when the door B of the chamber is closed thenit moves in contact with the trip I to swing the same downward into aninactive position to release the gravitycatch H, which then againassumes its normal vertical position. The trip I is provided at itspivoted end with a heel I3, abutting against the bracket E at the timethe trip I is swung into a lowermost inactive position, as indicated inFig. 1 and in dotted lines in Fig. 3. The gravity-catch H is provided inits hub with a longitudinal slot H, (see Fig. 8,) through which extendsa pin H2, secured to the cross-bar F2, so as to limit the swingingmotion of the said gravity-catch H from a vertical to a horizontalposition, as will be readily understood by reference to the drawings.

In order to prevent the tray C from tipping over accidentally when drawninto an outermost position, togetherl with the frame'F, as previouslyexplained, a retaining guide-rail J is provided, secured to each plate Eand adapted to extend over the corresponding side rails C2 of the trayat the time the tray is drawn outward, together with the frame F. Eachrail J is provided at its front end with a guard-rail J slightlyinclined forwardly and upwardly to enable the operator to readily guidethe rear cross-bar C1 down under the rail J and onto the guideway D whenplacing the tray G in position for pushing the tray back into thechamber A.

rI`he roller forming the projection U5 is preferably covered with rubberor similar material to reduce the noise incident to the roller coming incontact with the catch H.

The rear cross-bar F3 is held removably on the side rails F' of theframe to permit of removing the cross-bar F3 whenever it is desired todraw the frame F out of the chamber A for repairs or other purposes.

Although the device is shown in connection with a refrigerating-chamber,I do not limit myself to this application, as it may be used for otherpurposes, and I also do not limit myself to the detail constructionshown and described, as the same may be varied without deviating fromthe spirit of my invention.
